At this moment we know of only one "Earth"
however, a couple of moons are speculated to have liquid water for example Europa, though there is no definitive proof. Frozen water exists on its surface and does contain oxygen in its atmosphere, indicative that water could exists below the surface.
There a plans to launch a probe in 2022 to prove this once and for all.
What else can I help you with?
Are tsunamis on other planets?
Tsunamis are not known to occur on other planets in our solar system. The conditions required for a tsunami to form, such as the presence of large bodies of liquid water and tectonic activity, are not commonly found elsewhere in our solar system.
What is the differences between your planets and other planets?
earth is the only planet known to house liquid water and life
What planets are out there that's are not in your solar system?
These are planets that are in orbit around other stars, known as exosolar planets.
Were any other planets formed in the solar system other than the present eight planets?
Actually, there are 18 known planets in our solar system, as well as two known protoplanets. For a complete list of objects in the solar system, see the related links.
What are the planets composed with more liquid than solids?
None known; half the planets are mostly solid, the other half are mostly gas.
What other planets have there own planets?
As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.
How many planets have oceans?
There is only one planet known to have significant bodies of liquid water that cover a large portion of its surface, and that is Earth. Other planets in our solar system, like Mars and Europa, have evidence of liquid water in the past or under their surface, but not as extensive as Earth's oceans.
Do other planets orbit the sun?
Yes, other planets in our solar system orbit the Sun. There are eight known planets in our solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, all of which revolve around the Sun.
Your solar system is found between the planets?
The solar system is found between the orbits of two planets, with the innermost known planet being Mercury and the outermost known planet being Neptune. The solar system also consists of other celestial bodies such as dwarf planets, moons, asteroids, and comets.
What life-sustaining substance exists in vast amounts on earth but not on other planets of our solar system?
Liquid water is a life-sustaining substance that exists in vast amounts on Earth but not on other planets of our solar system. Water is essential for life as we know it, and the presence of liquid water is a key factor in determining a planet's potential to support life.
You are the only species in the solar system?
No, there are millions of species on Earth.It is not yet known whether there are other species, on other planets in the Solar System. None is known so far, but too little has been investigated to be quite sure.No, there are millions of species on Earth.It is not yet known whether there are other species, on other planets in the Solar System.

Do we assume that no life can live on other planets because humans can't?
No. There are life forms on Earth that can survive in extreme conditions where humans can't. The environment on Earth when life first emerged would have been toxic to us. If other planets have these conditions then they may support life. The main ingredient scientists believe to be necessary for life is liquid water. Earth is the only planet known to support liquid water on its surface, but we know very little about the planets that exist outside of our solar system. While it is unlikely that life exists on any of the other planets in our solar system, we have no way of knowing with current technology if planets in other solar systems support life.
